For purposes of illustration, it may be e1-iplained that the slitting and expand pg operations necessary to produce an expanded troughed fabric of the character referred to, may be and are successfully performed by the action of the slitting and expanding di preferably of the character disclose in m former Patent N 0. 1,049,632, dated January 7, 1913. These dies are operated within a suitable press, diagrammatically indicated in the drawings and designated by the refefiis to slit the sheet, and at the same time de form the slitted areas into a series of adjoining troughed expanded sections a (see Fig. i). It is this shape of material that is developed by the die-press as the blank is received from the primaryieedi'ng set, and it is this shape of material that is engaged and delivered by the dplivery feeding set.

Referring now to the features of the pres ent invention, it will be noted that the primary feeding set .essentially consists of a )air' of superposed-feeding rolls A and B.

referably each of these rolls A and B in cludes a plurality of flat-faced friction feeding-rollers 1 carried by the transverse shafts 2 and 3 of the upper and lower rolls A and B respectively, the said shafts having their opposite ends journaled in the bearing members at and 5 of the framework of the machine. With this arrangement, the feeding rolls A and B are adapted to receive a blank metal sheet from the feed table (5 and frietionally clamp, and engage the same therebetween to feed the press P. While the said shafts 2- and 3 are journaled in the bearing members above mentioned, they preferably project to hne side of the member 5 as will be clear from Fig. 1, to receive the gear wheels 7 and 8, and it will also be notedthat the shaft 3 in addition to having the gear 8 carries a ratchet wheehtl. Thus, as the gears-T and 8 inter-mesh, it is obvious-that the rolls A and B \villbe given an interrupted rotary feed movement when the shaft 3 is rotated intermittently-b3, the ratchet wheel 9, as will hereinafter inore'fully appear.

A distinctive feature of the present invention resides in the construction and action of the delivery feeding set arranged at the discharging side of the press to receive the troughed expanded r etal shape. This delivery feeding set ediiiprises a plurality of roll units 10, 11, and 2, which may be multiplied to any desired or required extent, and are preferably of duplicate construction. Upon an inspection of Figs. 3 and i, it will be seen that each of these delivery roll units 10, 11 and 12 includes a pair of superposed feed rolls Cand D, and each of these rolls in turn is preferably composed of a plurality of drawingdisks 13, of double tapered form. These disks 13 taper into a. relatively thin or narrow peripheral edge of a toothed or corrugated formation made up of uniform and regularly alternating notches 14 and the gripping'gprojections or teeth 14". With further reference to the structural fea tures of the delivery feed rolls C and D of each unit, it will be observed more especially from Fig 3, that the said drawing-disksl 'posite journal members 16 and 17. Thus,

the assembled feed rolls C audit) of each delivery roll unit,- present regularly alternating ridges and valleys which confornrto the folded or troughed formation of the expanded metal fabric or shape as it comes from the die-pres s 'PQ This will be clear from an inspectionof Fig. 5i, wherein the corrugated or toothed peripheries of the drawing-disks 13 oflthe superposed rolls C and D are shown in: vertical alinemeutso that the troughed' expanded metal shape emerging from the die-press will have the sinuous crownsor apices of its troughs en gaged between the drawing-disks 13 comprising the superposed feed rolls C and D of each of the delivery units 10, 11 and 12. See also Figs. 3 and 8. c p A novel and practical feature of then]- vention resides .in thespecial relation of the several delivery rolhunitslO, 11 and 12. This feature. preferably involves having the number of roll units eqnalito the relation ox-J" istin'gbetween therlength-of a half diamond mesh and the length ofan1nncutportioujof the strands betvveenadjacent. diamonds. For instance,if the length'of ahalf diamond mesh is'three times'the'length of thenncuti portion 9,1. tiefthree sets of rolls shouldbe usedfasshown in the drawings. It is also prefemhle to provide andlnaintain a pro-'- gressively steppedgsettlng. of the successive roll units, thatjis'to say, the drawing dislc; 13 of each succeednigdeln ery rollnmt are set with their gripp ng pro ect1onsspared 1a 1 proportional angular distance from the set, positions of the, silnilariiprojections of the w preceding roll unit,and"therefore in stepped relation-thereto. Accordingly, only one roll unit'at a' time grusp'snncnt portions of the strands,fso,that'the pos tive drawing action troughcd fabric is'withhithe passesof'all of the delirery roll units, the disks of the l'irs't cut stramlsas thcgripiot -the first rolls is rea pivoted pawl which i'\- hold in min" k leaseth and so on tln'onghout the entire series ment -n-ith the teethot .th iif'ratehet of delivery roll units, according t'o' n'liate'yer 9 and respectively h nuaink of number (if-said unitsa-re en'iployed.
